As shown in Figure 7 (b) shows, interior bilge block 30b comprises web portion 31 and the flange part 32,32 extended towards both sides respectively up and down from web portion 31 ..., its cross section is H shape.The flange part 32 of upside, 32(upper flange part 32b, 32b) extended respectively towards both direction (the thickness direction both sides of web portion 31) from the upper end of web portion 31.The flange part 32 of downside, 32(lower flange 32a, 32a) extended respectively towards both direction (the thickness direction both sides of web portion 31) from the lower end of web portion 31.Web portion 31 is identical with end chock 30a with the shape of flange part 32.On interior bilge block 30b, on each upper surface of upper flange part 32b, 32b of the thickness direction both sides of web portion 31, be placed with the flange 2a of other solar panel 2 respectively.By making bolt B insert the bolt hole of upper flange part 32b and the bolt hole of flange 2a, and screwing by nut N, just solar panel 2 can be fixed on chock 30.

As shown in Figure 3, two positions P1, the P2 on the solar panel 2 on top side, long side direction both ends in portion are upper by two dot point, and by two dot point on two positions P3, the P4 on the side, long side direction both ends of lower edge.That is, solar panel 2 is fixed on four fixed positions P1, P2, P3, P4.Fixed position P1, P2, P3, P4 are positioned at the equidistant position apart from bight (four angles of solar panel 2) adjacent separately.Each bar limit of the rectangle (in figure 3, only representing with double dot dash line on the solar battery panel 2 of central array) fixed position P1, P2, P3, P4 of support solar panel 2 four are formed by connecting is parallel with rafter 10 or chock 30.Specifically, the straight line being connected and fixed position P1, P2 and the straight line being connected and fixed position P3, P4 parallel with chock 30, the straight line being connected and fixed position P1, P3 and the straight line being connected and fixed position P2, P4 parallel with rafter 10.In addition, solar panel 2,2 side by side is in the vertical connected ... fixed position P1, P3 each linear array point-blank.In addition, solar panel 2,2 side by side is in the vertical connected ... each straight line of fixed position P2, P4 also arrange point-blank.

The cross section rigidity of chock 30 is set, to make the chock 30 at the two ends up and down of the setting position being positioned at each solar panel 2,30(in the present embodiment for all chocks 30,30 ...) deflection distribution (deflection curve) equal.As long as it is equal to make the deflection of end chock 30a and interior bilge block 30b distribute, the deflection of the chock 30,30 at the two ends up and down of the setting position being positioned at each solar panel 2 just can be made to distribute equal.

Below, the relation of the flexural rigidity of end chock 30a and interior bilge block 30b is described.Distributing to make the deflection of end chock 30a distributes equal with the deflection of interior bilge block 30b, preferably cross section rigidity is set as meeting following formula:

2E _ai _a=E _bi _b(formula 3)

E _a: the Young's modulus of end chock 30a

E _b: the Young's modulus of interior bilge block 30b

I _a: the cross section rigidity of end chock 30a

I _b: the cross section rigidity of interior bilge block 30b

In addition, in the present embodiment, because chock 30 is all formed by identical material (aluminium alloy), thus E _a=E _b, therefore, (formula 3) will become 2I _a=I _b.This is because on the chock 30a of end, effect has the weight of each solar panel 2 half, and effect has the weight (i.e. the weight of one piece of solar panel 2) of the weight of solar panel 2 half on the upside of it and solar panel 2 half of downside on interior bilge block 30b.That is, by being set to 2I _a=I _b, the deflection of all chocks 30,30 just can be made to distribute equal.

Equidistance is stretched out towards outside respectively from a pair rafter 10,10 in the both ends of chock 30.The extension elongation X of chock 30 is 0.210 times of chock 30 total length.Below, to the numerical value of extension elongation X according to being described.The stress be applied in the Basic Design of pallet on chock 30 is determined by the position of two rafters (supporting point).In addition, in the present embodiment, solar panel 2 by four-point supporting, but when studying extension elongation X, supposes there is uniform load to calculate in the upper effect of beam (chock) on fixed position P1, P2, P3, P4.

Usually, when in the total length of beam, effect has a uniform load w, acting on bending moment on beam maximum is when beam is supported at two ends, when namely the extension elongation X of beam is 0.Now bending moment (maximum bending moment) M of the central portion of chock is following formula.

M＝w·l ²/8

W: uniform load

L: distance between the fulcrum

On the other hand, the bending moment M of the extension at the both ends of beam _xwith the bending moment M of the central portion of beam _atime equal, the bending moment that beam produces is minimum.At this, represent with following formula:

M _X＝－wX ²/2

M _A＝[｛w（X＋l） ²－wX ²｝/2l]·l/2－w/2（X＋l/2） ²

If the uniform load w of solar panel 2 is set as general numerical value and 9.8N(1kgf), and calculate and meet M _x=M _athe extension elongation X of chock, then it is 0.210 times of chock 30 total length Y.

But, in the present invention, the bending moment that chock 30 produces is limited in the 2/3(=wl of maximum bending moment M ²within)/12.Meet the extension elongation X of the chock of the above-mentioned upper limit if calculate, then it is the length of the scope of 0.085 ~ 0.410 times of chock 30 total length Y.

According to the solar panel pallet of above-mentioned this structure, action effect as described below can be obtained.

By making the both ends of chock 30 stretch out from rafter 10, the simply supported beam of two supports can be utilized reduce the bending moment of the span central authorities vicinity being applied to chock 30.Therefore, compared with the situation not making the both ends of chock stretch out, the cross section second moment of chock 30 can be reduced, and sectional area can be reduced by thinning wall thickness, therefore, the lightweight of chock 30 can be realized.Wherein, when in the scope of 0.085 ~ 0.410 times extension elongation X of chock 30 being set in chock 30 total length Y, because the bending moment be applied on chock 30 is less than 2/3 of maximum bending moment, therefore ideal.Particularly, when the extension elongation X of chock 30 being set as 0.210 times of chock 30 total length Y, the bending moment be applied on chock 30 is minimum.

Like this, by limiting the bending moment be applied on chock 30, can reduce and be applied to pallet stress on the whole, and can light weight be provided and there is the solar panel pallet 1 of sufficient intensity.In addition, the extension elongation X of desirable chock 30 can be calculated according to the load of solar panel 2.

In addition, in the present embodiment, owing to supporting a rafter 10 with two pillars 50,50, therefore very stable.In addition, by arranging stull 59 between the pillar 50,50 supported the upside of a pair rafter 10,10 respectively, thus the structure of not easily laying across is formed.In addition, because each rafter 10,10 is supported obliquely by pillar 50, solar energy face 2 therefore can be made effectively to receive sunlight towards the direction of the sun.

In addition, in the present embodiment, because rafter 10 is connected with pillar 50 by gusset 55, therefore, strengthened at the interval rafter 10 being configured with gusset 55, thus the flexure of span centre is diminished.That is, due to the substantial distance between the fulcrum of rafter 10 can be shortened, the bending moment be applied on rafter 10 can therefore be reduced.By this, the wall thickness of the thinning rafter 10 of energy, and can sectional area be reduced, therefore, the lightweight of rafter 10 can be realized.

Wherein, by being set in the scope of 0.075 ~ 0.150 times of rafter 10 total length M by the length L of gusset 55, solar panel pallet 1 can be made light-weighted effective.That is, if gusset 55 is shorter than 0.075 times of rafter 10 total length M, then fully bending moment cannot be reduced, on the contrary, if gusset 55 is than 0.150 double-length of rafter 10 total length M, then gusset 55 weight will increase, and the overall light-weighted effect of pallet is diminished.

In addition, in the present embodiment, be defined as by the fixed position that gusset 55 pairs of rafters 10 are fixed and meet above-mentioned (formula 1) and (formula 2) simultaneously, to make rafter 10 both ends stretch out from the position of the fulcrum (position of gusset 55) of itself and pillar 50, the bending stress of the fulcrum vicinity being applied to rafter 10 can be made to disperse.Therefore, can the bending moment be applied on rafter 10 be reduced, the wall thickness of the thinning rafter 10 of energy, and can sectional area be reduced.By this, rafter 10 further lightweight can be realized.

In addition, owing to being provided with raised line 58 on gusset 55, rafter 10 is provided with the groove 14 engaged with raised line 58, therefore easily and correctly can carries out the location of the mutual alignment of gusset 55 and rafter 10.In addition, because raised line 58 and groove 14 play the effect of ribs, the stiffening effect of diagonal angle fagging 55 and rafter 10 can therefore be obtained.

In addition, because rafter 10 and chock 30 are made up of the extrudate of aluminum alloy, the lightweight of solar panel pallet 1 entirety can therefore be realized.In addition, the precision of each component can be improved, and can easily and correctly carry out installation exercise, and excellent weatherability and attractive in appearance can be realized.In addition, aluminium alloy is excellent in recycling property, therefore, after pallet is aging, can recycle material.

In addition, in the present embodiment, the deflection distribution laying respectively at the upper edge of the setting position of solar panel 2 and the chock 30,30 of lower edge is equal, and by parallel with rafter 10 or chock 30 for each bar limit of support solar panel 2 four rectangles that P1, P2, P3, P4 are formed by connecting (illustrating with double dot dash line in figure 3).By this, as shown in Figure 9, the deflection of upper and lower each chock 30 at fixing point P1 and P3 place is equal all the time, and the deflection of upper and lower each chock 30 at fixing point P2 and P4 place is equal all the time.Therefore, the position relationship that the straight line connecting fixed position P1, P3 of each solar panel 2 and the straight line being connected and fixed position P2, P4 can remain parallel to each other all the time.Therefore, even if solar panel 2 tilts relative to original installation surface, also distortion hardly, thus can guarantee flatness.By this, can suppress to be applied to solar panel 2 distortional stress with it.In addition, because chock 30 can allow distortion to a certain degree (even if distortion also produces twisting stress hardly on solar panel 2), therefore, the sectional area of part can be reduced, and lightweight can be realized further.

Above, be illustrated for implementing embodiments of the present invention, but the present invention is not limited to above-mentioned execution mode, can appropriate change design without departing from the scope of the subject in the invention.Such as, in the above-described embodiment, rafter 10 and chock 30 are made up of the extrudate of aluminum alloy, but the present invention is not limited to this.Such as, both can be formed by stainless steel alloy, also can by being formed after sheet material bending machining.

The side of rafter seat 110 is formed the groove 116 extended along long side direction.Groove 116 is formed in the downside of groove portion accepting groove 111b.Groove 116 is the parts engaged with the raised line 182 of gusset 180 described later.

As shown in FIG. 13 and 14, rafter seat 110 is connected by gusset 180 with pillar 140.At rafter seat 110 with on the connecting portion of pillar 140, the upper surface of pillar 140 abuts with the lower surface of rafter seat 110, and rafter seat 110 and pillar 140 are sandwiched between pair of horns fagging 180,180.

Gusset 180 side-looking rectangular in shape, it is made up of the extrudate of aluminum alloy.The long side direction (direction of extrusion) of gusset 180 configures along the long side direction of rafter seat 110.Two edges up and down of gusset 180 are formed with ribs 181 respectively.Ribs 181 bends towards outside (clamping outside during rafter seat 110) relative to the plate portion of gusset 180.Gusset 180 is suitably formed bolt hole (not shown).The axle portion of bolt B is inserted bolt hole.

As shown in figure 14, the face contacted with rafter seat 110 of gusset 180 is formed with raised line 182.Raised line 182 extends along the long side direction of gusset 180.Raised line 182, by mutually embedding with the groove 116 of rafter seat 110, plays the effect of the location of gusset 180 and rafter seat 110.In addition, in the present embodiment, gusset 180 is formed with raised line 182, rafter seat 110 is formed groove 116, but also can form groove on gusset 180, and form raised line on rafter seat 110.

At the connecting portion place of rafter seat 110 with gusset 180, the head of bolt B is housed in the sidepiece accepting groove 111b of rafter seat 110, and the axle portion of bolt B is given prominence to from sidepiece accepting groove 111b.Run through the bolt hole of gusset 180 from the axle portion that sidepiece accepting groove 111b gives prominence to, thus also give prominence to from gusset 180.If nut N to be tightened in the axle portion from the outstanding bolt B of gusset 180, then carry out the engaging portion 113 of counter-lateral quadrents accepting groove 111b by the head of bolt B and nut N and gusset 180 clamps.By this, rafter seat 110 and gusset 180 can be fixed.

At the connecting portion place of pillar 140 with gusset 180, the head of bolt B is housed in the long side accepting groove 141a of pillar 140, and the axle portion of bolt B is given prominence to from long side accepting groove 141a.Run through the bolt hole of gusset 180 from the axle portion that long side accepting groove 141a gives prominence to, thus also give prominence to from gusset 180.If nut N to be tightened in the axle portion from the outstanding bolt B of gusset 180, then by the head of bolt B and nut N, the engaging portion 143 of long side accepting groove 141a and gusset 180 are clamped.By this, pillar 140 and gusset 180 can be fixed.

By this, rafter seat 110 is connected by gusset 180 with pillar 140.

Below, the length L(of diagonal angle fagging 180 is with reference to Figure 13) and rafter seat 110 and gusset 180 weight between relation be described.Such as, suppose that the length of rafter seat 110 is 4000mm, when engaging with pillar 140 not using gusset, the weight of rafter seat 110 is 14kg.At this, situation when being connected with pillar 140 by rafter seat 110 gusset 180 that uses length L to be 200mm carries out tentative calculation, due to the distance between the fulcrum of rafter seat 110 reality can be shortened, therefore, the bending moment be applied on rafter seat 110 can be reduced, and the sectional area of rafter seat 110 can be reduced, thus rafter seat 110 can be made the weight of about 10kg.The weight (two pieces) of gusset 180 is about 1kg.Because the total weight of rafter seat 110 and gusset 180 is about 11kg, the lightweight of about 3kg therefore can be realized.

In addition, the length L of diagonal angle fagging 180 is the situation of 350mm when carrying out tentative calculation, and the weight of rafter seat 110 is about 7kg, and the weight (two pieces) of gusset 180 is about 2kg.Because the total weight of rafter seat 110 and gusset 180 is about 9kg, the lightweight of about 5kg therefore can be realized.

That is, if increase gusset 180, then the lightweight of rafter seat 110 can be realized.But, increase gusset 180, the weight of gusset 180 correspondingly can be made to increase.Therefore, it is preferable that, the balance between the recruitment considering the light-weighted effect of rafter seat 110 and gusset 180 weight brought because making gusset 180 increase carrys out the length L scope of set angle fagging 180.According to foregoing, it is preferable that, when rafter seat 110 is 4000mm, the length L of gusset 180 is set as 300mm ~ 600mm.By this, the length L of gusset 180 is in the scope of 0.075 ~ 0.150 times of rafter seat total length.More preferably, preferably the length L of gusset 180 is set as 350mm ~ 500mm.By like this, the length L of gusset 180 is in the 0.088(0.0875 of rafter seat 110 total length Y) in ~ scope of 0.125 times.

As shown in Figure 10, equal distance is stretched out towards outside by the both ends of the rafter seat 110 of pair of posts 140,140 supporting respectively from the pillar 140,140 of both sides.The extension elongation X of rafter seat 110 is 0.210 times of rafter seat 110 total length.Below, to the numerical value of extension elongation X according to being described.The stress be applied in the Basic Design of pallet on rafter seat 110 is determined by the position of two pillars (supporting point) 140,140.In addition, in the research of following extension elongation X, suppose there is uniform load to calculate in the upper effect of beam (rafter seat).

Usually, when in the total length of beam, effect has a uniform load w, acting on bending moment on beam maximum is when beam is supported at two ends, when namely the extension elongation X of beam is 0.Now bending moment (maximum bending moment) M of the central portion of chock is following formula.

M＝w·l ²/8

W: uniform load

L: distance between the fulcrum

On the other hand, the bending moment M of the extension at the both ends of beam _xwith the bending moment M of the central portion of beam _atime equal, the bending moment that beam produces is minimum.At this, represent with following formula:

M _X＝－wX ²/2

M _A＝[｛w（X＋l） ²－wX ²｝/2l]·l/2－w/2（X＋l/2） ²

If the uniform load w of solar panel 2 is set as general numerical value and 9.8N(1kgf), and calculate and meet M _x=M _athe extension elongation X of chock, then it is 0.210 times of rafter seat 110 total length Y.

But, in the present invention, the bending moment that rafter seat 110 produces is limited in the 2/3(=wl of maximum bending moment M ²within)/12.Meet the extension elongation X of the chock of the above-mentioned upper limit if calculate, then it is the length of the scope of 0.085 ~ 0.410 times of rafter seat 110 total length Y.

As shown in figure 18, to be configured to its direction of extrusion identical with the flute length edge direction of top accepting groove 111a for the first stiffener 150.First stiffener 150 is formed as longer than common packing ring, thus can run through for along the adjacent multiple bolt B of flute length edge direction, B.Specifically, the length dimension of the first stiffener 150 to be set as than the outboard end of a pair second stiffeners 170,170 being located at rafter 130 both sides between distance.

Second stiffener 170 is made up of the extrudate of aluminum alloy.Second stiffener 170 is configured to make the direction of extrusion be the direction (long side direction of rafter 130) orthogonal with the direction of extrusion of the first stiffener 150.As shown in figure 20, the second stiffener 170 comprises baseplate part 171 and foot 172, second stiffener 170 cross section is L-shaped.The central part of baseplate part 171 is formed with bolt hole 173.The axle portion for rafter 130 being fixed on the bolt B on rafter seat 110 is inserted in bolt hole 173.

Foot 172 is formed as giving prominence to downward from an end of the Width (direction orthogonal with the direction of extrusion) of baseplate part 171.Foot 172 is configured in the side away from rafter 130.The bottom of foot 172 abuts with the upper surface (upper surface of engaging portion 113) of rafter seat 110.

The other end (side contacted with the locking plate 132a of rafter 130) i.e. side edge part of the Width of baseplate part 171 forms to press the end of locking plate 132a and carries out locking press section 174.The lower surface of press section 174 is formed with groove 175, and this groove 175 can insert for the portion of standing up 133 be formed on the Width leading section of locking plate 132a.

As shown in figure 18, the second stiffener 170 is configured in the Width both ends of rafter 130 respectively.If screwed the second stiffener 170 by bolt B and nut N, then the locking plate 132a of rafter 130 can be pressed by the second stiffener 170 and engaged.Meanwhile, the foot 172 of the second stiffener 170 can be pressed against in the engaging portion 113 of rafter seat 110.

Below, the step of rafter seat 110 and rafter 130 being fixed is described.

As shown in figure 17, first, the axle portion of bolt B, B is inserted to bolt hole 153,153 from lower surface (be formed with bolt rotation and prevent the face with ridge 156a, the 156b) side of the first stiffener 150.Then, first stiffener 150 and bolt B, B are inserted from the end of top accepting groove 111a, and with the state making the axle portion of bolt B outstanding from the gap between engaging portion 113,113, move to desired position (position to rafter 130 is fixed) along flute length edge direction.Now, because the first stiffener 150 is formed as slightly less than the inside dimension of top accepting groove 111a, therefore it can not be stuck on the inner surface of top accepting groove 111a.In addition, the guiding ridge 114 due to engaging portion 113 lower surface is inserted in the gathering sill 154 of baseplate part 151 upper surface, and therefore the first stiffener 150 can move swimmingly along top accepting groove 111a.In addition, because the bottom of temporary fixed wall portion 152 abuts with the bottom of top accepting groove 111a, therefore the angle of inclination of the first stiffener 150 can kept under constant state, the first stiffener 150 is easily moved in the accepting groove 111a of top.If make the first stiffener 150 be moved to assigned position, then make bolt Va insert the screw hole 115 of rafter seat 110 and the screw hole 155 of the first stiffener 150, the first stiffener 150 is temporarily fixed on rafter seat 110.

In this state, rafter seat 110 is transported to scene.When carrying, because the first stiffener 150 is temporarily fixed on rafter seat 110, therefore the first stiffener 150 can not loosen and can carry with stable state.

Then, in the job site of solar panel pallet, rafter seat 110 is arranged on pillar 140, and rafter 130 is set between the axle portion of the bolt B outstanding from rafter seat 110, B.It is orthogonal with the long side direction of rafter seat 110 that rafter 130 is configured to its long side direction, and between the rafter seat 110,110 being erected at front and back a pair.In addition, rafter 130 is installed in advance the dog screw Vb being used for positioning relative to the rafter seat 110 of its long side direction.Dog screw Vb is nailed on from the downside of locking plate 132a in advance, and makes the head of dog screw Vb give prominence to from the bottom surface of locking plate 132a in advance.By making the head of dog screw Vb abut with the bight of the upper surface of rafter seat 110, the long side direction position of rafter 130 just easily can be determined.

In addition, because the first stiffener 150 is temporarily fixed on desired setting position, the axle portion of therefore outstanding bolt B becomes the guide of rafter 130 relative to the setting position of rafter seat 110.Therefore, as long as between axle portion rafter 130 being arranged on bolt B, B, just can easily carry out the location on the long side direction of rafter seat 110.By this, can making, operation is set and become easy.

Then, the mode pressed with the leading section of the locking plate 132a to rafter 130 arranges the second stiffener 170,170.The mode that second stiffener 170 is positioned at downside with foot 172 declines from the top of bolt B, thus the axle portion of bolt B is inserted in bolt hole 173.In addition, nut N be arranged on the leading section from the outstanding bolt B axle portion of the baseplate part 171 of the second stiffener 170 and screw.Now, the head due to bolt B is in the state rotating and be subject to bolt rotation and prevent from stoping with ridge 156a, 156b, therefore easily can carry out screwing of nut N.Screwed by above-mentioned, bolt B and nut N clamp the first stiffener 150, second stiffener 170, engaging portion 113 and locking plate 132a by screwing.In addition, the engaging portion 113 of foot to rafter seat 110 of the second stiffener 170 presses, and the end that press section 174 presses locking plate 132a is locking to carry out.After completing nut N formally screwing in bolt B, both screw Va can be pulled down, it also can be made to keep installment state.

According to the solar panel pallet 101 of above-mentioned this structure, action effect as described below can be obtained.

In the solar panel pallet 101 of present embodiment, because rafter seat 110 is connected with pillar 140 by gusset 180, therefore, is strengthened at the interval rafter seat 110 being configured with gusset 180, thus the flexure of span centre is diminished.That is, due to the substantial distance between the fulcrum of rafter seat 110 can be shortened, the bending moment be applied on rafter seat 110 can therefore be reduced.By this, the wall thickness of the thinning rafter seat 110 of energy, and can sectional area be reduced, therefore, the lightweight of rafter seat 110 can be realized.

By being set in the scope of 0.075 ~ 0.150 times of rafter seat 110 total length Y by the length L of gusset 180, solar panel pallet 101 can be made light-weighted effective.That is, if gusset 180 is shorter than 0.075 times of rafter seat 110 total length Y, then fully bending moment cannot be reduced, on the contrary, if gusset 180 is than 0.150 double-length of rafter seat 110 total length Y, then the weight of gusset 180 will increase, and the overall light-weighted effect of pallet is diminished.

In addition, owing to being provided with raised line 182 on gusset 180, rafter seat 110 is provided with the groove 116 engaged with raised line 182, therefore easily and correctly can carries out the location of the mutual alignment of gusset 180 and rafter seat 110.In addition, because raised line 182 and groove 116 play the effect of ribs, the stiffening effect of diagonal angle fagging 180 and rafter seat 110 can therefore be obtained.

Because rafter seat 110 and pillar 140 are made up of the extrudate of aluminum alloy, the lightweight of solar panel pallet 101 entirety therefore can be realized.In addition, the precision of each component can be improved, and can easily and correctly carry out installation exercise, and excellent weatherability and attractive in appearance can be realized.In addition, aluminium alloy is excellent in recycling property, therefore, after pallet is aging, can recycle material.

On the other hand, pillar 140 according to the present embodiment, owing to can arrange bolt B in each side, therefore any direction all around can arrange stull 104.In addition, the rational height of bolt B also can free setting.In addition, in the scope that stull 104 can not interfere each other, stull 104 can be connected with multiple side.

By making the both ends of rafter seat 110 stretch out from pillar 140, the simply supported beam of two supports can be utilized reduce the bending moment of the span central authorities vicinity being applied to rafter seat 110.Therefore, compared with the situation not making the both ends of chock stretch out, the cross section second moment of rafter seat 110 can be reduced, thus sectional area can be reduced by thinning wall thickness.By this, the lightweight of rafter seat 110 can be realized.Wherein, when in the scope of 0.085 ~ 0.410 times extension elongation X of rafter seat 110 being set in rafter seat 110 total length Y, because the bending moment be applied on rafter seat 110 is less than 2/3 of maximum bending moment, therefore ideal.Particularly, when the extension elongation X of rafter seat 110 being set as 0.210 times of rafter seat 10 total length Y, the bending moment be applied on rafter seat 110 is minimum.

Like this, by limiting the bending moment be applied on rafter seat 110, can reduce and be applied to pallet stress on the whole, and can light weight be provided and there is the solar panel pallet 101 of sufficient intensity.

In addition, in the present embodiment, owing to supporting a rafter seat 110 with two pillars 140,140, therefore very stable.In addition, by arranging stull between pillar 140,140 adjacent in the vertical and between pillar 140,140 adjacent in the horizontal, thus the structure of not easily laying across is become.In addition, because each rafter 130,130 tilts relative to horizontal direction, solar panel 102 therefore can be made effectively to receive sunlight towards the direction of the sun.

On the other hand, according to above-mentioned this rafter seat 110 and the fixed structure of rafter 130, action effect as described below can be obtained.

Utilize the first stiffener 150, the contact area with engaging portion 113 can be increased.Even if because towards lift solar panel 102 direction blast (negative pressure) and cause rafter 130 by towards being pulled (rafter 130 pulls towards upborne direction) away from the direction of rafter seat 110, the pressing force (dead-end pressure from bolt B head) of the first stiffener 150 movement upward also can be dispersed on very wide area and act in engaging portion 113.By this, due to the face pressure be applied in engaging portion 113 can be reduced, the distortion of engaging portion 113 (curling) can therefore be suppressed.Thus, very large negative pressure can be born.

Particularly, in the present embodiment, the first stiffener 150 have and top accepting groove 111a groove sidewall 112a, 112b upper end between the roughly equal width dimensions of distance, therefore, the width dimensions of the first stiffener 150 can be increased to greatest extent.By this, the contact area of the first stiffener 150 and engaging portion 113 can be increased, and the tolerance performance to negative pressure can be improved.In addition, the baseplate part 151 due to the first stiffener 150 is formed thicker than engaging portion 113, therefore can make to concentrate the dead-end pressure of effect to be dispersed in very wide scope from bolt B head and transmit.

In addition, due to the first stiffener 150 be configured to make pair of bolts B adjacent along flute length edge direction in the accepting groove 111a of top, the shaft portion of B do not run through, and the distance between being formed as than the both ends of the second stiffener 170,170, therefore can increase the contact area of the first stiffener 150 and engaging portion 113 further.By this, the face pressure be applied in engaging portion 113 can be reduced further.In addition, by increasing the first stiffener 150 and the contact area of engaging portion 113, the frictional force of the first stiffener 150 and engaging portion 113 can be increased, and the first stiffener 150 can be suppressed to the slip of flute length edge direction.In addition, owing to just can be fixed two bolt B, B by first stiffener 150, therefore, with arrange the situation of the first stiffener 150 respectively for each bolt B, B compared with, it is consuming time to reduce arranging of the first stiffener 150.

In addition, on the first stiffener 150, prevent because temporary fixed wall portion 152 and bolt rotate the effect playing ribs with ridge 156a, 156b, therefore, the lightweight of the first stiffener 150 can not only be realized, and effectively can increase the cross section rigidity of the first stiffener 150.On the second stiffener 170, because the effect of ribs plays in foot 172, therefore, the lightweight of the second stiffener 170 can not only be realized, and effectively can increase the cross section rigidity of the second stiffener 170.

In addition, the Width both ends of the engaged plate 132a of engaging portion 113, the first stiffener 150 and the foot 172 of the second stiffener 170 clamp, therefore, engaging portion 113 is pressed by from positive and negative two faces, thus further can suppress the distortion of engaging portion 113.

In addition, the Width both sides of rafter 130 are pressed by the second stiffener 170, and by bolt B and screwing of nut N by firmly locking, therefore, can improve the constant intensity of rafter seat 110 and rafter 130.Particularly, be L-shaped because the second stiffener 170 is formed as cross section, therefore the power that screws of bolt B, nut N is easily delivered in locking plate 132a and engaging portion 113, thus can increase the power pressed locking plate 132a.

In addition, the portion of standing up 133 due to locking plate 132a stretches in the groove 175 of press section 174, therefore can improve the constant intensity of rafter seat 110 and rafter 130 further.Specifically, by making the portion of standing up 133 engage with groove 175, reliably prevent rafter 130 from offseting in the direction of the width.In addition, due to the contact area of locking plate 132a and the second stiffener 170 can be increased, the frictional force produced between rafter 130 and the second stiffener 170 can therefore be increased.Therefore, the skew of rafter 130 on its long side direction can also be prevented.
